Kulug Bagha

Kulug Bagha (fl. 840) was one of nine ministers of the Uyghur Khaganate. A rival of Khan Kurebir of Mongolia, he invited 80,000 Yenisei Kirghiz warriors to invade the khaganate, killing Kurebir and leading to the fall of the empire.

Biography
In 839, the usurping minister Kurebir invited 20,000 Shatuo horsemen from Inner Mongolia to invade the Uyghur Khaganate, and they helped him to depose the Ediz dynasty, forcing Khan Hu of Mongolia to commit suicide. During Khan Kurebir's first year of reigning, a famine and epidemic brought ruin to the khaganate, and Kulug Bagha became an opponent of him. He fled to the Kyrgyz tribe and invited them to invade from the north. 80,000 Yenisei Kirghiz horsemen sacked the capital of Ordu Baliq in central Mongolia, razing it to the ground. They beheaded Kurebir, and the Ediz were restored. However, the Kirghiz went out of control, destroying several cities throughout the empire and burning them down. This would lead to the fall of the empire in 847.
